Air Driven Double Diaphragm

Pumps

The BEST Diaphragm Pumps in the World!

ABOUTALL-FLO

ALL-FLO is committed to thepursuit of designing and man-ufacturing the highest qualityproduct available to industry. Since the beginning in 1986,ALL-FLO engineers have usedtheir extensive knowledge oftoday’s engineered materials,advanced air system logic andmanufacturing techniques todevelop the superior group oflube-free, air-operateddiaphragm pumps found inthis catalog. Every pump isperformance engineered andquality built to provide trouble-free service under thetoughest conditions.

S I M P L E O P E R A T I O NDouble diaphragm pumps areoperated by compressed air orany non-flammable com-pressed gas. The pumpingstroke begins as air is deliv-ered by the air distributionsystem, putting pressure onone diaphragm and then theopposite diaphragm. The twodiaphragms are linked togetherby a common rod. The pump-ing stroke on one side issimultaneously the suctionstroke on the opposingdiaphragm alternately drawingfluid in one side while dis-charging fluid from the other side.

PERFORMANCE ENGINEERED

ALL-FLO HAS THE RIGHT PUMPFOR ANY APPLICATION...Classic Performance pumps offeryears of trouble-free service.Performance Plus pumps offertrouble-free service plus enhancedoperating features.The Specialty Performance 3/8˝pump – the revolution in low flowpump technology.

NO STALLOUTS DUE TO FREEZING...Stallout due to ice formation in theair system is virtually eliminateddue to the insulating quality of allplastic construction plus the abilityto slow air expansion and velocitywithout compromising performance.

NO VENT HOLES...There are no vent holes in the ALL-FLO air valve. Vent holes needed toprevent stalling in competitivepumps allow corrosive fumes toenter and destroy valuable compo-nents. Additionally, if a diaphragmruptures, fluid leakage cannot berouted to a safe containment zone.The sealed ALL-FLO air valve allowscontainment of fluid and preventsfumes from entering air system.

PERFORMANCE ENGINEEREDPTFE DESIGN...Superior PTFE overlay design doesNOT require reduced diaphragm rodstroke, which reduces pump capacityby 20% on competitive pumps. Allback-up diaphragms for PTFE over-lays are Santoprene which offers achemically resistant “second line ofdefense”.

THERMOPLASTIC DIAPHRAGMS...offer superior chem-ical and abrasionresistance andincreased cycle life.The wide range ofapplications thatthese materials canaddress also make

ordering the correct pump much easier.

MAINTENANCE TIME REDUCED...due to uniform product design. Allmodels share the same design conceptfrom 1/2˝ pumps to 3˝ pumps. Thesize of the components just get larger.If you know how to rebuild one size...you can easily rebuild any size.

INVENTORY REDUCTION...because metallic and plastic pumpsall share the same air systems,diaphragms, O-rings, balls and insome cases valve seats. To furtherhelp minimize inventory requirements,1-1/2˝ and 2˝ models share the sameair systems, diaphragms and valveseat components.

ALL PLASTIC AIR SYSTEMS...in both metallic and plastic pumps prevent destruction of air system components from corrosive atmos-pheres or diaphragm ruptures. Nobrass or aluminum components areused within the air systems.

SIMPLE ORDERING CODES...confused by complex ordering codesrequired by some manufacturers—not with ALL-FLO. All models areeasily associated with materials andhave a simplified model number asshown on page 4.

MAX-PASS™ VALVE SYSTEM FOR LARGE SOLIDS...

Look for the Max-Pass™ symbol.

LARGER CAPACITY...per stroke than competitive modelsmeans less wear on moving parts.

BSP...compatibility is accomplished throughthe use of slotted flanges on the 1˝,1-1/2˝ and 2˝ models and BSP com-patible threads are available on othermodels when requested.

PROCESS CONTROL...Solenoid Control is optional forSpecialty Performance andPerformance Plus pumps. Cyclecounting is optional for most pumps.

ATEX AND CE...certification and quality control proce-dures have been obtained for all models.

Cycle Counting

Every time a cycle is completed, an impulse is sent from the cyclecount valve to a data acquisition center for automated input to aPC, PLC, relay or switch. Measuring how much fluid is being transferred through the pump based on the number of elaspsedcycles is a convenient method for:1) monitoring how much additive a system has received or 2) adding a precise dose of fluid based on a set number of cycles.Cycle based maintenance rather than time interval maintenance isideal for systems where the fluid is hazardous or abrasive. Elapsedcycles can be monitored from any workstation within a network.The cycle count valve is integral to the air valve. The sensor at thebottom of the air valve is provided (see photo). The configurationfor data acquisition and control is not provided.To order a pump with the cycle count valve assembled on the pump, add Option Code –A42 to the pump model number.

OPTIONAL PUMP ACCESSORIES

PROCESS CONTROL FOR ALL-FLO PUMPS

Solenoid Control (Optional for Specialty Performance and Performance Plus)

The solenoid control valve is used for remote, electrical control of an All-Flo pumpthrough a PC, PLC, relay or switch. The solenoid control valve can be operated from anyworkstation in a network.The solenoid control valve replaces the air valve assembly. The solenoid is mounted ontothe intermediate using an adaptor plate. When energized, air is delivered to one side ofthe pump while simultaneously exhausting the other side. The reverse occurs when thevalve is de-energized. World standard connections and coil voltage are available. The control signal is a solutionto ‘on demand’ fluid transfer requirements or the pump can be used to monitor flow rate.To order the solenoid control valve, add –A43-XX to the model number with the voltagerequirement replacing the ‘XX’.

DRUM KITSThe many advantages of diaphragm pumps make them ideal for drum evacuation. All-Flo has taken the guesswork out of this application. When ordering an All-Flo pumpwith a drum mounting kit, the bottom port is positioned for immediate assembly, and auniversal bung adaptor and compatible suction tube are provided. All the components necessary for the perfect drum pump!

Add a ‘D’ after the model code (e.g., PED-05) to receive the drum configuration. Drum mounting kits are available for pumps up to 1˝ in size. Contact your All-Flo distributor for compatible pump models.

Both the Cycle Counter and Solenoid control valves are designed to make your All-Flo pump an integral component ofyour process. Chemical, ink, paint pigment and adhesive transfer are just a few of the literally thousands of applicationsrequiring process control. Note: The cycle count and solenoid control valves can be used on pumps 3/8˝ and larger. Contact your All-Flo distributor for pricing and application information.
